University of Anchorage Alaska Metallurgy Molybdenum Lab 1 and research report Weld A287 Metallurgy Eli Ringelenstein, Instructor Objective: to find and document characteristics of AL 6061 – T 6, AL 6063 – T6, AL 5052 – H32, 3003 – H 14 starting off with AL 6061 – T6 we see that it’s in composition is comprised predominantly of aluminum being from 95.8% to 98.6% with a maximum of .7 percent FE 0.042 0.35% CR 0.15 to 0.4% Cu, 0.8 – 1.2% Mg a maximum of 0.15% Mn 0.4 – 0.8% Si, and a maximum of 0.15% Ti.
The application for the specific alloy of aluminum is listed as aircraft fittings camera lenses/mounts couplings Marine fittings and hardware electrical fittings connectors decorative miscellaneous hardware hinges and pans magneto parts brake pistons hydraulic pistons appliancefittings valves valve parts and bike frames. The sites I reference give it a 95 on the Burnell hardness a 120 on the Knoop hardness of 40 on a Rockwell “A” test and a 60 on a rock will “B” test along with the 107 on the Vickers hard this test.Continuing on restraint tested ultimate tensile strength was listed at 310 MPA also known as 4000 pounds per square inch, it’s tinsel yield strength was listed as 276 MPA or 4000 pounds per square inch. You on Gratian at break about 12% for specimen 1/16 of an inch or 1.6 mm thick, you on Gratian at break 17% for specimen half-inch or 12.7 mm diameter.The source also noted that some of the data points listed were designated with an AA note this note specified that the data points were retrieved from the AA or aluminum Association Inc. and
